technical field

The invention relates to an internal light source ball string type photocatalytic water purification box, which belongs to the technical field of water environment protection.

Background technique

In recent years, with the rapid development of my country's industrialization and the further improvement of agricultural intensification, the produced industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of untreated or incompletely treated sewage is discharged into rivers, lakes and other water bodies through river and canal systems at all levels, resulting in the overall deterioration of the water quality of rivers and lakes. An important measure of protection. At present, there are more and more forms and sources of pollutants, and the types of pollutants dissolved or suspended in water bodies are becoming more and more diverse and complex. In the traditional biological purification technology, plants have the characteristics of selective absorption. At the same time, the types of pollutants that microorganisms can decompose and metabolize are limited, and the adaptability to pollutants is poor, especially for some refractory substances and substances with strong biological toxicity in industrial sewage. , is not only difficult to remove, but also endangers the survival of plants and microorganisms, so its application and purification efficiency are greatly limited.

In recent years, the application of photocatalytic technology in water environment protection and treatment has been paid more and more attention. Its representative nano-TiO2 powder has the advantages of high chemical stability, light corrosion resistance, insoluble in water and non-toxicity. The degraded compound can be degraded into H ₂ O and CO ₂ through the photocatalysis of TiO ₂ under the condition of ultraviolet radiation, especially for the removal of refractory organic pollutants in water, so TiO ₂ nano photocatalysis Degradation method is a new technology of water treatment with great application prospects. At present, the main utilization forms of nano-TiO ₂ mainly include nano-powder catalyst method and loading method. The nano-powder catalyst method is very difficult to recover, separate and reuse nano-TiO ₂ powder during the implementation process, and it is still in the experimental stage. , and the loading method is to fix the TiO ₂ nanometer powder on a certain carrier to prepare the loaded TiO ₂ photocatalytic material. This material is easier to separate liquid and solid in water treatment, and it is more convenient to reuse. There are many types of carriers used. .

In addition, the ultraviolet irradiation intensity at the reaction interface also greatly limits the popularization and use of photocatalytic reaction devices. The ultraviolet content in natural light sources is less, and for the loading matrix with a large specific surface area, the irradiation area of the light source is small. It is difficult to obtain a satisfactory purification effect. Therefore, it is urgent to develop a series of high-efficiency photocatalytic purification devices with large specific surface area and large irradiated area at the same time to adapt to the increasingly diverse trend of pollutants in modern water bodies. positive meaning.

The working principle of the present invention is as follows: the purification box is placed in the water body, and its flow control window 8 is placed in the upstream direction. During the day, the solar panel 3 converts light energy into electrical energy and stores it in the storage battery of the control box 5, and the ultraviolet generator in the control box 5 generates ultraviolet light, which is transmitted through the side light optical fiber 7 and directly irradiates the surface of the purification ball 9 On the surface, the titanium dioxide photocatalytic film coated on the surface can oxidize and reduce the refractory organic pollutants in the water to H ₂ O and CO ₂ under the action of ultraviolet rays, thereby reducing the content of pollutants in the water and purifying the water body;

At night, the electric energy stored in the battery continues to maintain the work of the ultraviolet generator, so that the water-permeable box can realize the function of purifying water continuously around the clock.

Since the photocatalytic reaction requires a certain reaction time, too high water flow rate through the water-permeable box will make the photocatalytic reaction incomplete, thereby reducing the purification efficiency, and the low water flow rate in the box can promote the thorough photocatalytic reaction, but the water-permeable The exchange of water between the box and the outside world is reduced, resulting in a decrease in the overall purification efficiency, so the flow in the purification box needs to be controlled within an appropriate range.

This device adopts a louver-shaped permeable window to control the amount of water exchanged inside and outside: when the external water flow is small, adjust the knob 2 on the top to make the opening of the flow control window 8 and the side permeable window 14 to the maximum, and the external sewage passes through the front part. The flow control window 8 enters the purification box and flows out through the lateral water permeable windows 14 on both sides and the flow control window 8 at the rear. In this state, the exchange resistance between the external water body and the water body in the purification tank is small, which is beneficial to improve the purification efficiency.

When the external water flow is moderate, adjust the opening of the front flow control window 8 to the maximum, and appropriately reduce the opening of the rear flow control window 8 and the lateral permeable window 14, thereby increasing the water flow exchange resistance between the box and the outside world , reduce the flow velocity and flow in the box, so as to achieve the purpose of improving the purification efficiency.

When the external water flow rate is large, adjust the openings of the flow control windows 8 at the front and rear to a smaller state, and appropriately increase the openings of the lateral permeable windows 14 on both sides, thereby reducing the front of the purification box. Inflow, most of the water enters and flows out of the purification box through the side water-permeable window 14. In this state, not only can the water flow velocity in the purification box be effectively reduced, and the purification efficiency can be improved, but also the photocatalytic film can be prevented from being directly impacted by the high-speed water flow on the purification ball in the box.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should also be regarded as the protection scope of the present invention.
